Lamp house grease

Hi everybody.
I am regreasing two Zeiss lamp houses.
Any recommendation for a grease?
Thanks.

Could you post photos of the lamp houses you are referring to. They may be innocent.

I am sure...
There are remainings of old grease on it, which solidified and lamp adjustment knobs ceased to move.
Here a photo of one of them from the internet.
I do not have them around to make a photo.

Hi Petro,
so is the problem is the adjusting screws? How hot a do they become in use? This determines the choice of lubricant.

It is hard to say now as I cannot start them and I do not have previous experience with them.
I have ordered some antistuck with working temperature up to 1000C. If it will be to dense I will use G-1/3 OLELUBE vaseline. It has working temperature up to 200C.
And then I will see.

The copper-rich greases, typically specified for use on the back of brake-pads,
e.g. https://www.commaoil.com/productsguide/view/6/220
would probably do the job nicely.

At the end I wrote to a microscope service and repair company located in Poland
They recommended this grease.
GRIZZLYGREASE No. 3

I was not able to get it but I think G-1/3 will do the job. It has 175 C working temperature maximum and no dropping point.
